What is Mini solar panel
Mini Solar panel is a kind of solar panel, but the packaging method is different. By laser cutting the solar cell into small pieces, the required voltage and current are made, and then packaged. Due to its small size, it generally does not use the packaging method similar to the solar photovoltaic module, but uses epoxy resin to cover the solar cell and bond it with PCB circuit board. It has the characteristics of fast production speed, compression resistance and corrosion resistance, beautiful appearance and low cost.
The panel size can be customized according to the size required by the guests, and the working voltage and current can be customized. Generally, the solar drip panel is used to charge the battery of solar charger, solar lamp, toy and other applied electronic products. The working current is measured under the simulated standard illumination intensity of 1000w/m2, 25 ℃, AM1.5. Due to different light intensity, the voltage and current emitted will also change in a day. In sunny days, the power generated by solar panels can be calculated by 4 hours.

Manufacturing Process of Mini Solar Panel
Solar drip panel is a kind of solar panel, but the packaging method is different. By laser cutting the solar cell into small pieces, the required voltage and current are made, and then packaged. Due to its small size, it generally does not use the packaging method similar to the solar photovoltaic module, but uses epoxy resin to cover the solar cell and bond it with PCB circuit board. It has the characteristics of fast production speed, compression resistance and corrosion resistance, beautiful appearance and low cost.
technological process:
Cutting – assembly – Detection – glue dripping – vacuum pumping – baking – spot inspection – film coating – packaging
Tools / raw materials
Solar cells (monocrystalline silicon cells, polycrystalline silicon cells)
Laser dicing machine
Thermostatic soldering iron
Photovoltaic welding strip and flux
Tester
Vacuum box
oven
- Select single crystal and polycrystalline battery chips according to customer needs
- Cut the battery into corresponding sizes according to the required voltage and current.
Generally, the open circuit voltage of a solar cell is about 0.5-0.6V
Voltage of glue dropping plate = number of small cells *0.6v
The current of the dripping plate is proportional to the area of the small battery
During laser scribing, attention should be paid to the set power, frequency and scribing speed of the laser. The scribing depth should be kept at 1/2—2/3, and cannot be cut through.
- For the welding of battery pieces, use multiple thin welding strips as a bridge to connect the marked battery pieces in series one by one. Before welding, the welding strip must be soaked in flux for a period of time and used after drying.
Constant temperature soldering iron shall be used for welding, and the welding shall be fast and accurate
- Paste and fix
Stick double-sided adhesive tape on the adhesive dripping base plate, and stick the welded battery pieces on it. The welding strip passes through the small hole of the glue dripping base plate to the back and is welded to the pad
- After welding, it is necessary to check. Put the semi-finished glue dropping plate on the test bench, and preliminarily measure the current and voltage values through the irradiation of iodine tungsten lamp
- Place the semi-finished products that pass the test on the glue dropping table, and take glue a and B according to the quality ratio. Mix AB components and stir evenly. Inject the mixed glue into the glue dropping bottle, and then inject the glue from the glue dropping bottle into the front of the patch board, and use tools to make the glue on the patch board evenly distributed.
- Vacuum the battery module filled with glue to make the glue completely fit the base plate without bubbles. The vacuum pumping time is about 5 minutes.
- Put the vacuum treated glue dropping board into the oven and heat it to solidify the glue. It is about 60 degrees, and the time is about 2 hours, which needs to be determined according to the performance of the glue.
- For finished product inspection, in order to ensure that the battery is not short circuited or damaged after high temperature baking, it is necessary to test the current and voltage of the rubber dropping plate again.
- For finished product inspection, in order to ensure that the battery is not short circuited or damaged after high temperature baking, it is necessary to test the current and voltage of the rubber dropping plate again.
- Pack and pack. After packaging, the drip plate has high light transmittance, good sealing, beautiful appearance, long service life, and close combination between colloid and silicon crystal plate.

What does Customer say about FBELE Company
We saw FBELE on the forum. At that time, we thought that the enterprise’s technical articles were very thorough and in-depth, and its social responsibility was also strong. This year, we just need to have new product development, so we found fbele and asked them to purchase samples. The speed was very fast and the quality was good, waiting for the implementation of the project!
In 2019, I contacted FBELE through my friend’s introduction. My friend has cooperated with FBELE for 10 years, and the cooperation is very happy, and then recommended it to me We bought fbele products. At present, we are very satisfied with the quality and delivery date. I will also recommend them to my friends.
